Total Wattage Formula:
From: | To: |
Definition: This calculator computes the total electrical load by summing the wattage of individual devices.
Purpose: It helps determine the total power consumption of multiple electrical devices, useful for circuit planning and energy management.
The calculator uses the formula:
Where:
Explanation: The calculator simply adds up the wattage of all devices entered to give the combined electrical load.
Details: Proper wattage calculation ensures electrical circuits aren't overloaded, helps in selecting proper wire gauges, and assists in energy consumption planning.
Tips: Enter the wattage for each device (minimum one required). The calculator will sum all non-empty fields. Values must be ≥ 0.
Q1: Where can I find a device's wattage?
A: Check the device's label, manual, or specifications sheet. Alternatively, use a wattage meter.
Q2: Should I use running wattage or peak wattage?
A: For continuous load calculations, use running wattage. For circuit breakers, consider peak wattage.
Q3: How does this relate to amperage?
A: To convert to amps, divide total watts by voltage (e.g., 120V in US households: Amps = Watts/120).
Q4: What's a typical household circuit capacity?
A: Standard circuits are 15 or 20 amps (1800-2400 watts at 120V). Large appliances may need dedicated circuits.
Q5: Should I add a safety margin?
A: Yes, it's recommended to keep sustained loads below 80% of circuit capacity for safety.
